1) Is this what was referred to in the movie "The Menu" where they were taking the tour in the beginning and talking about the 152 day aging process for meat, but the 153rd day would bring chaos? 2) Why is there such a precise known number for that issue? Don't bacteria grow differently? It just seems odd that 152 days would definitely be ok and 153 days would definitely kill.
